The MAX9206/MAX9208 deserializers transform a high-
speed serial bus low-voltage differential signaling
(BLVDS) data stream into 10-bit-wide parallel LVCMOS/
LVTTL data and clock. The deserializers pair with seri-
alizers such as the MAX9205/MAX9207, which gener-
ate a serial BLVDS signal from 10-bit-wide parallel
data. The serializer/deserializer combination reduces
interconnect, simplifies PCB layout, and reduces board
size.
The MAX9206/MAX9208 receive serial data at
450Mbps and 600Mbps, respectively, over board
traces or twisted-pair cables. These devices combine
frequency lock, bit lock, and frame lock to produce a
parallel-rate clock and word-aligned 10-bit data.
Serialization eliminates parallel bus clock-to-data and
data-to-data skew.
A power-down mode reduces typical supply current to
less than 600µA. Upon power-up (applying power or
driving PWRDN high), the MAX9206/MAX9208 estab-
lish lock after receiving synchronization signals or serial
data from the MAX9205/MAX9207. An output enable
allows the outputs to be disabled, putting the parallel
data outputs and recovered output clock into a high-
impedance state without losing lock.
The MAX9206/MAX9208 operate from a single +3.3V
supply and are specified for operation from -40°C to
+85°C. The MAX9206/MAX9208 are available in 28-pin
SSOP packages.
